Shuttle valve switch failure

darrenm · Jan 9, 2013

Had the dreaded three amigo's this morning had a look on hawkeye and is saying shuttle valve switch failure I have already changed shuttle valve switchs last year looks like next weekends job

you better do this then ABS Mod - LAND ROVER CLUB V.I. , option B...and it'll be fixed for good(but only for SVS failure...other faults will still trigger the 3 amigos)

You beat me to that link by seconds...was just about to post the same.

Mine's also got SVS 'electrical failure' and this spring I'll also be undertaking 'Option B'.

Please let us know how you got on, especially as I've had one crack at this and couldn't lift the ABS unit high enough to get at the allen screws beneath in the modulator unit. I'd love to know if you achieve this and how.

Cheers
Lea

for me it was easyer cos i've got a spare modulator which i modified ... swapped them and now i have another modified one

Well I did option b this morning as no body was in work so we will see took me 40mins inc having a brew

How did you lift the ABS unit high enough? Sorry haven't watched the vid link yet..

40 Mins... Things are looking up

LeaUK · Jan 15, 2013

Watched the vid, seems like with a short angled allen key you can get at the allen screws?

Straight forward undo the 2 electrical connectors then undo four bushs take brake lines of brackets which are onto bulk head then just lift it up I just held it up while I undid the 3 x 4mm hex holding shuttle valve in place

LeaUK · Jan 16, 2013

I just couldn't lift mine up for fear of damaging the brake lines going to the top of the ABS....The 3 x 4mm hex holding the shuttle valves are beneath the ABS right, so lift up the ABS (mine only lifts 75mm safely) and slide a right angled hex driver underneath?

Took the abs lines out in the end, over to the bench with the ABS unit! Purchased a new solenoid ABS Modulator Shuttle Valve Repair Kit (Wabco) SWO500030 Island 4x4 - Specialists in Land Rover and Range Rover Parts and accessories for all models. UK and worldwide mail order. (just in case) - although mine was fine!

Replaced the shuttle valve and carried out Option B ABS Mod - LAND ROVER CLUB V.I.

SORTED!!!!

SO HAPPY, after a year of constant 3 amigos - not again.

and a pic of the unit with mods....

I left the original socket in when reassembly as it provides a seal against any oil, note the orings ;-)

Unclipping the lines from the bulkhead helps lift it a wee bit more, u can get a 1/4 drive socket in underneath.
